Classic US Stamps - 1863 - 1920

Hi,

First sorry for my english, I am not very fluent.
I have found in a family collection, numerous US stamps from (i think) the 1860s for the oldest up to the 1910s (or 1920s).

I am not an expert, I launched some research but I have several contradictory information.
I understood that used stamps were cheaper than unused ones. Most of these stamps are unfortunately obliterated.
BUT, stamps are very old, I tell myself that some may interest a collector, and stamps have particularities on many of them (over-pricing with ink for example, or under-pricing, obliteration with hole etc...)

Can a passionnate stamp collector tell me the years and possibly the values #8203;#8203;of these stamps?

I attach the picture taken from the albums (preview)
Of course, I can provide better quality picture if necessary.
Also a small preview of indian, swedish, puerto rico, honduras stamps.

Thanks a lot for your help.

Value will not be much. Most are very common. The $1 Parcel Post stamp is a better one but still only a few $.

There also appears to be a forgery of a 2¢ stamp in one of the scans.

Good eye!
